Great app from the UX/UI perspective. The progression from saving in the browser and only requiring an account later is very nice as well. Perhaps the only thing missing is a start over button.

As for exercise selection, it returns a lot of niche moves and exotic variants. Which makes it interesting but probably not a good fit for someone who would be most likely to use this app, ie. isn't an intermediate+ body builder already. Occasionally the recommendations are just bad (crunches).

Certainly a welcome addition for someone looking for variety though.
